Application March 25, 1938, Serial No. 197,974, 8 Claims. (CI. 12-51) This invention relates to shoe upper forming and sheet metal element thus embracing the heel end pressing machines of that type wherein a thin, of the shoe on this form and extending forwardly preferably sheet metal member, embraces the along opposite sides thereof, Cooperating with heel end and sides of the shoe upper, while the these wings l4 and I5 are side presser members 5 shoe is supported on a. form, this sheet metal I6 and I1, respectively, supported at the upper 5 member being pressed against the shoe by a pair ends of a pair of levers l8 and 19. These levers of side presser members. are fulcrumed at 20 and 2| and their lower ends The present invention has for one object to are connected together by toggle links 22 and provide improved means for pressing the thin 23. For the pu po 0f adjustment, these toggle 0 embracing member against the heel end of the links are shown as provided with slots 24 in which 10 shoe so as to smooth and flatten the b ck eam ride transverse pins 25 at the lower ends of the at the heel end of the shoe upper when there is arms 13 a adjusting SCIeWS 25 being such a seam and to prevent the side presser memp yed to de e mine the limit of outward motion bers from forming a ridge between them. of the cross pins 25 in these slots.

From this back portion it has 41, provide a yielding connection between the extending forwardly, a pair of Wings 14 and I5 lever 33 and the rod 41 such that on depressing which are so formed as to extend about the sides the handle 35, the rod 41 is moved upwardly and 55 of the upper of a shoe held by the form 4, the the bell crank lever 42 rocked in a direction to 55 force forwardly the bar I, and with it the element l2, against the heel end of a shoe in position on the form, as shown in Figure 4, where an opera slipper is shown in dotted lines in position between the wings I and i5 of this element. On upward motion of the handle 35 sufficient to break the toggle, the side presser members I5 and I! are moved outwardly by the spring 2'! and the rod 41 is depressed, swinging the bell crank lever 42 in the opposite direction, thus permitting the bar I to be retracted, as by the action of a spring 54 surrounding it, and reacting between the inner side of the head G5 and the base 55 of the socket 56 in which the inner end of the spring 54 is housed. It will thus be seen that by' depression of the handle 35, the pressing element I2 is moved against the rear or heel end of the shoe, thus to smooth and condense the heel seam portion and the wings M and I5 are moved inwardly against opposite sides of the shoe by the action of the presser members l6 and El. By reason of the use of metal in the presser member l2, heat applied to theform will be effective to heat this metal and result in an ironing effect on the outer face of the shoe.

Due to the generally wedge shape of the form, its upper portion being narrower than its lower portion, and the pressure of the side presser members against the shoe carried on the form, an effect to force the form downwardly is produced, which causes a wiping action of the presser element l2 toward the top margin of the shoe while it exerts inward pressure also.- This has a desirable effect in smoothing the upper, and extending the outer layer of its upper at itstop edge above the top edge of the lining so as to render the lining edge less prominent in the finished shoe.

From the foregoing description. of an embodiment of this invention, it should be evidentto those skilled in the art that various changes and modifications may bemade without departing from the spirit or scope of this invention as defined by the appended claims.
